TONSILLOTQME.

Application'led .Tune 24, 19.21. Serial No. 480,185.

root tissues of the tonsil are severed, usually by a wire snare,yand are temporarilyleft unbound with the result'thatrthe operation is ordinarilyv` attended with the loss of con"-` siderable blood.` It is therefore the primary object ofthe present inventionto provide a tonsillotome embodying means whereby tissues may be-readi-lyand conveniently tied or boundin al secure manner before being severed so .thai-,the operation will not result Y in therloss of any appreciable amount of A blood, will be less dangerous to perform, and j jwill permit of a more thorough subsequent throat atthe leisure of,

exaniinationot the -the surgeon. Y Y

More specifically the presentA invention has .as its object to provide in connection with Ya Vfor the support of a looped ligature in such a mannerthat after the tonsil to beremoved hasfbeen passed through the lumen of the instrument, the ligature may be pulled uponV and 4automatically:tied and knotted about the tissues Aat, theibase of the tonsil and remain tied to said tissues even after removal of the instrument'froin the mouth cavity. so that'not only is loss of blood prevented, but furthermore vthe severed tissues may be left without attentionl temporarily and until y.the surgeon` is Vprepared tol'make his :further infspection and otherwise complete theopera- "tioni 1 i Afurther object of the inventionv is to so construct the instrument that the ligature to be.` employed `nia-y be readily threaded therethrough, tied-ina slipV knot, and pro- Vvided .with a loop arranged in' a concealed manner within the lumen oil the 1 instrument; r

YA Vfurther objectief the invention is to provide novel means for-retainingthe liga-4 ture loop within the lumen of the instrument and insuch positionthatitwill not intertonsillotome embodying a Wire snare, means tere with the loop of the wire snare by the contraction or" which the tonsil tissues are to'be severed. y

The instrument embodying the invention comprises a shank which is indicated in general by the numeral l and which is pro- V.vided with a longitudinally extending bore 2. The shank is also provided upon its upper side with a tubular guide indicated by the numeral 3,. the boreot this guide being indicated bythe numeral 4L. At its Ylorivard rend the shank l is provided with a lumen indicated in general by the nun'ieral and olthe usual elliptical forni, the linnen being A disposed with its major axis.transversely of the a-Xis oit' the shank as illustrated in Figures l, 5 and 65 and the opening oi the lumen 'being indicated by the numeral 6. it the juncture ofthe forward end of the shank with the rear side of the lumen 5,7`the shank is broadened inaforward direc-.tion as indicated by the numeral 7 and this broadened portion is iat upon'its opposite sides and its surfaces merge with the corresponding surfacesof the lumen 5. As clearlyshown in Figure 6 of the drawing,the bore 2 oit the shank l is gradually increased in width or flared throughout that portion of its length which extends through the broadened por Vtion 7 of the shank andas indicated by the numeral 8, and the Wall ol the lumen 5 is formed in its inner. side with a Vcircuin'jerential groove or channel 9 the ends of which communicate-with the flared end 8 of the bore 2. The numeral 10 indicates a wire snare and the loop of this snare is indica-ted by the numeral l1 and is` normally disposed within the groove o r channel 9,.the sides of Vthe loo extendino' sione' the side wells ofV D Y C Y tlie'wideiied portion Softhe bore 2 asbest shown :in llllieuie 6 of theidrawing, so that VWhenthe in ruincnt is prepared 'tor use,
